B E D S P RI N G SPECIFICATION forming part of Letters Patent No.465,539, dated December 22, 1891.

Application filed July 16, 1891- Sen'al No. 399,721- (No model.)

To aZZ whom it may concern;

Be it known that I, JOSEPH ROSE, a citizen .of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented a new and useful Bed-Spring, of which the following is aspecification.

My invention relates to improvements in spring bed-bottoms, beingdesigned as an improvement of the patent issued to me in this class ofinvention hearing date January lat, 1890, and numbered 419,218; and ithas for its object to counteract the defect in having the facing-hooksconnecting the pairs of coilsprings together from standing too highabove the plane of the top coil of the springs, and to avoid arough-surface bed, and to provide a spring bed-bottom in which the wholeup per and under surfaces of the springs will be on the same plane, andto overcome the objection of having sharp projecting ends or corners,and also to so connect the springs so that the same shall retain theirproper shape and elasticity; and with these objects in View theinvention consists of the improved construction of springs and themanner in which the same are connected to attain the objects aimed for,which will be hereinafter more fully described, illustrated in theaccompanying drawings, and specifically pointed out in the appendedclaim.

In the accompanying drawings, Figure 1 is a top view of a springbed-bottoin constructed in accordance with my invention. Fig. 2 is adetail in perspective showing a section of the same and a portion of theadjacent frame.

Referring to the accompanying drawings, the frame A, between which andto which the springs comprising the bed'bottom are connected, iscomposed of the two rectangular wire frames a, formed to the proper sizeand shape by bending and connected together at their meeting ends in anysuitable manner. The coiled springs B, located within said frame, are ofthe ordinary duplex type in which the coils taper from both ends to thecenter, and are each constructed and provided with the same details, thebottom and top coils C f the springs also being similarly constructed inorder that the bottom surface will be similar to the top, and thusprovide a reversiblespring bed-bottom. At the point at which the top andbottom coils O of the springs'are to be locked the same are providedwith the vertical shoulders or offsets D, around which shoulders oroffsets the ends of the upper and lower coils are passed from theoutside and upover the top, forming a loop E, which provides a lock orjoint for the bottom and top coil, which serves to retain the springs inthe proper shape and prevent the same from collapsing or spreading. Fromthe loop E, where the top coil passes over the said offsets orshoulders, the same then passes out.- ward in a horizontal direction,the bottom and top coils being parallel, and both forming the arms F, atthe outer ends of which areformed the double hooks G, provided with theinwardly-facing hooks g and the outwardly-facing hooks g.

Both the bottom and top coils of each spring are further provideddirectly opposite the ver tical offsets or shoulders previouslymentioned with the inward depression H. In arranging the springs withinthe rectangular frames inclosing the same the tWo outer longitudinalrows are first placed in position, while the intermediate and centralrows are subsequently secured to said outer rows and to eachother. Thedouble hooks at the terminals of the horizontally-extending arms F ofthe two outside rows are first clinched over the sides of therectangular frames to, comprising the bed-bottom frame, while theintermediate rows of springs are secured to the rows of springs adjacentthereto by means of the outwardly-facing hooks g of the double hook G,located at the terminal of the horizontally-extending arms 1 engagingover the bottom edge of the depression H in the top and bottom coils ofeach spring, while the inwardly-facing hook 9 projects into and withinthe space formed by said depression in the wire, and thus throws thesaid arms all on the same plane as the top of the springs which theyengage and those from which they protrude. After the requisite rows ofsprings have been placed within the frame to complete the bed-bottom ofthe desired size the two central rows are then connected and joinedtogether, the rows of springs being arranged from the outside of theframe inward, as stated. The central depression inthe top and bottomcoils of the central pairs of springs are therefore directly opposite toeach other,

TOO

and the same are connected together by means of the connecting-clips I,provided with the inwardly-facing hooks t' and the outwardlyfacing hookst", which engage over the bottom edge of said depressions in the top andbottom coils of the springs, while the inwardlyfacing hooks project intoand Within the depressions in the same manner as the double hooks at theterminals of the horizontally-extending arms, as described.

To securely retain the hooks and springs in connection with each otherand to forma rigidly constructed bed bottom, binding- Wires K are nextpassed longitudinally from one end of the frame to the other. The saidwires are first attached to the end of the frame and are next passedunder the top coils and over the bottom coils of the adjacent springs. Each binding-wire being provided with a horizontal depression 7a, thatengages the inwardly-facing hooks of both the arms F and theconnecting-clips I and project into and within the space formed by thedepressions in the top and bottom coils of each spring, and passing onthrough each adjacent spring and having the same connection with the topand bottom coils and the double-faced hooks, as described, the freeterminal of r the said Wires are secured to the opposite ends of theframe, and thus completes a bed-bottom'the top and bottom surfaces ofwhich are unbroken horizontal planes, all the connections and jointsbeing seated and located beneath the planes of the top and bottom coilsof each spring.- By this construction, as previously stated, sharpprojecting ends or corners are avoided and an exceedingly elastic andcomfortable bed-bottom produced.

- The construction of the improvement is now thought to be apparentwithout further de scription.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

In a bed-bottom, the springs, the top and bottom coils of which areprovided with an inwardly-depressed portion, and Vertical offsets orshoulders around which the ends of the coils are looped and extend outtherefrom in a horizontal direction and terminate in the inwardly andoutwardly facing hooks, which latter engage the bottom edge of thedepression of the next adjacent'springs, and which former project withinthe same, center connecting-clips having the inwardly and out wardlyfacing double hooks joining the bottom edges of the facing depressionsof the central rows of springs and seated within said depressions, andthe longitudinal bindingwires passing under the top coils and over thebottom coils of each spring, and each wire being provided with ahorizontal offset or depression engaging the inner hook of said doublehooks and projecting within the-depressions in the top'and-bottom coilsof the springs, saiddepressions serving to hold or incloseall of saidfastenings in the same ora lower plane than the plane'of the topandbottom coils of the spring, substantially as set forth.

In testimony that I claim the foregoing as my own .I have hereto affixedmy signature in presence of two witnesses.
